Abstract
Model for the shell and tube heat exchanger has been established. This Model enables the complete design and rating of shell-and-tube heat exchanger, using equations recommended by TEMA (Tubular Exchanger Manufacturing Association) for the calculations of heat transfer coefficients and pressure drops of the liquid in. the shell-side. The theoretical model is divided into four parts: first part is devoted to the heat transfer model, which deals with the energy equations needed for sizing or.ratii1g different types and arrangements of shell-¬and-tube exchangers. Pal1 2, is a pressure loss model for calculating the pressure losses in both tube-side and shell-side under different design and. operating conditions. Part 3, deals with flow-induced tube vibration, a phenomena which encountered chietly on the shell-side of shell-and-tube heat exchangers. Today, an exchanger design is unacceptable unless it has been checked lor vibration damage. This means that vibration damage on exchanger tubes is unlikely to occur at any sections through its shell-side under normal operating conditions. The last part deals with exchangers constructed of different tubing materials, namely, low carbon-steel, stainless steel, copper and titanium materials. The capital cost and the total cost of heat exchangers made of these selected materials, in relation to low carbon steel exchanger are estimated.
A computer program is developed for the thermal design of such exchanger type. Computational results showing the effects of the system parameters as: the heat capacity ratio, Pressure losses in tub-side, pressure losses in shell-side. number of tube passes, baffle cut and space ratios. fouling thickness and tubing materials on the size and cost of heat exchangers with single-phase applications are presented in graphical forms.
